Convert degrees Rankine to degrees Delisle with this simple formula:

degrees Delisle = ( 671.67 - [°R] ) × 5 / 6

Insert the [°R] temperature measurement in the formula and then solve to find the result.

For example, let's convert 50 °R to degrees Delisle:

50 °R = ( ( 671.67 - 50 ) × 5 / 6 ) = 518.058333 °De

The Rankine scale and the Delisle scale are both used to measure temperature. Read on to learn more about each of them.

What Is Rankine?

The Rankine scale is an absolute temperature scale that uses absolute zero as the starting point, much like the Kelvin scale. The key difference between the Rankine scale and the Kelvin scale is that an increment of one degree rankine is equal to an increment of one degree Fahrenheit, not Celsius as in the Kelvin scale. The base of the Rankine scale starts at absolute zero, thus 0 degrees rankine are equal to −459.67 degrees Fahrenheit.

Rankine can be abbreviated as R, and are also sometimes abbreviated as Ra. For example, 1 degree Rankine can be written as 1 °R or 1 Ra.

What Is Delisle?

The Delisle scale is a temperature scale that sets a fixed zero point equal to the temperature of boiling water. The Delisle scale is uses incrementing degrees as the temperature decreases. It runs from 0 degrees at the boiling point of water to 150 degrees at the the freezing point.

Delisle can be abbreviated as De; for example, 1 degree Delisle can be written as 1 °De.
